Using 127.0.0.4 responses from relays.osirusoft.com to reject mail means that you are very likely to reject a significant quantity of perfectly legitimate mail from non-spammers. that response code is used for the entries provided by SPEWS (www.spews.org) which lists addresses by the ARIN-registered range in many cases. It is certainly the case that barring typos at SPEWS the listed address space is in fact controlled by ISP's which do little or nothing about spammers using their networks, but sadly that description applies accurately to such minuscule providers as Sprint, Qwest, Verio, Exodus, and so forth. Large chunks of their networks are listed in SPEWS because one or two spammers have taken up residence on a few addresses surrounded by innocent bystanders. There are fine logical arguments for running a blacklist this way, but the fine logical arguments do not change the fact that the result is the rejection of legitimate mail, aka 'collateral damage.' >At the moment I don't appear to be losing any emails that I want, but I am >noticing that the daily volumes are WAY down from my previous life with Web* >mail.. It is always wise to keep an eye on what your server is rejecting. It is all logged. >Also, I have quite a few rules < ... > = error in my ruleset.

Routing to error means that the mail is rejected before it is actually received. -- Bill Cole [EMAIL PROTECTED] ############################################################# This message is sent to you because you are subscribed to the mailing list <[EMAIL PROTECTED]>.
